FOG-001 for advanced solid tumors with certain gene changes
This trial tests a new drug, FOG-001, alone or with other treatments, for people with advanced solid tumors that have specific changes in the WNT pathway genes. It aims to see if the drug can shrink tumors or slow their growth.
Phoenix, ArizonaAges 18 years+ - NCT05898789Recruiting
Virtual rehab program for cancer survivors
This trial tests a virtual (online) rehabilitation and exercise program for people after breast, colorectal, head and neck, or certain blood cancers. It may help improve recovery and daily functioning by supporting safe activity and targeted rehab after treatment.
Toronto, OntarioAges 18 years+ - NCT05845450RecruitingPhase 2
Pre-surgery targeted drugs for selected colorectal cancer tumors
This trial tests targeted cancer drugs given before planned colon or rectal surgery. It may help by trying to shrink the tumor and treat specific tumor “targets” found in your stored pathology sample, depending on your tumor’s genetics and marker tests.
Milan, Lombardia/MIAges 18 years+ - NCT05803382RecruitingPhase 1
Adding a new drug to capecitabine for metastatic colorectal cancer
This Phase 1 study tests a new anti-cancer drug (ZEN003694) added to the usual chemotherapy capecitabine. It is for adults with colorectal cancer (and possibly other cancers) that has spread or cannot be removed and has continued despite prior standard treatment.
Irvine, CaliforniaAges 18 years+ - NCT05732623Recruiting
Study of early colorectal cancer risk factors in younger adults
This study looks at factors that may contribute to early-onset colorectal cancer (cancer in the colon or rectum diagnosed at a young age). It compares people with early-onset colorectal cancer to people without cancer to better understand possible causes and risks.
Denver, ColoradoAges 18–49 - NCT05705492RecruitingPhase 2
Olanzapine to help cancer-related weight and appetite loss
This Phase 2 trial tests whether olanzapine can help people with advanced cancer who are losing weight and not eating enough. It looks for improvements in appetite and weight while you receive your first-line palliative cancer treatment.
Portland, OregonAges 18 years+ - NCT05630794RecruitingPhase 1
Safety study of ONC201 for preventing colon polyps
This trial tests a drug called ONC201 to see if it can safely help prevent colon polyps from coming back in people at high risk. You will take the drug for about 12 weeks and have a second colonoscopy to check results.
Ann Arbor, MichiganAges 18 years+ - NCT05611034RecruitingPhase 1
Testing a lung treatment for colorectal cancer spread to lungs
This Phase 1 trial tests a targeted treatment delivered to the lungs for colorectal cancer that has spread to the lungs. It aims to see if the approach is safe and can reach lung tumors, especially when there are multiple lung lesions.
Toronto, OntarioAges 18–70 - NCT05321134Recruiting
